In this experiment, the student observed reactions that occur to identify two unknowns. The known solutions are mixed with each of three different reagents. Using these reactions as a reference the student developed a systematic set of tests to identify the unknown solutions.

The Great Eastern Earthquake
by Aditya Ponugupaty
The Great Eastern earthquake and the tsunami that occurred on March 11, 2011 caused the meltdown of three nuclear reactors within several days, and four hydrogen explosions. Huge quantities of radioactive elements have been continuously released into the air and water. It will induce an epidemic of cancer, as people inhale the radioactive elements, eat radioactive vegetables, rice, and meat, and drink radioactive milk and teas.
Magnesium burns bright in color and the ash weights more than the metal, since MgO is not a gas.

Victoria Boller holding the limiting reactant demo.
Limiting Reactants determine how much product that can be produced in a given reaction. Students learn that they will experience limiting reactants as a manager of a company. Managers take risks purchasing items to be sold at a higher cost, thus the number of items on hand is called the limiting reactants. Steve holds a flask that has 10 cm of magnesium metal and 50 ml of hydrochloric acid. Victoria holds a flask with 3 cm of magnesium metal and 50 ml of HCl. The reaction produces hydrogen gas which fills the balloon. The size of the balloon is determined by the amount of limiting reactant present.
Stoichiometry concerns predicting a theoretical amount of product before the reaction occurs, so that when the actual value is produced in the experiment a percent yield can be calculated. Students learned that when managers of clothing stores like Von Maur order goods they have a theoretical dollar amount expected from the sale. However, changes in the weather or a bad economy can cause the store to discount and the actual money generated from the sale is compared to the theoretical in order to determine if the product should be ordered again. Students allowed the product to dry over night and will calculate the actual copper produced from the reaction to determine the percent yield.
One of the most impressive and significant features of the Periodic Table of Elements is the appearance of vertical groups of elements, which form "families". Elements that are in the same "family" or "group" form compounds that are similar in formula and physical properties.

The Hyman Fire Piston demonstrates the rise in temperature when a fixed mass of gas is compressed. A portion of tinder supported inside a transparent cylinder is ignited when the contained air is compressed by a hand operated piston.
Dakota Chappell uses the combined law apparatus to show that when the volume is decreased the pressure increases and the temperature increases.
The combined gas law is a gas law that combines Charles's law, Boyle's law, and Gay-Lussac's law. There is no official founder for this law; it is merely an amalgamation of the three previously discovered laws. The combined gas law can be used to explain the mechanics where pressure, temperature, and volume are affected. For example: air conditioners, refrigerators and the formation of clouds, and also use in fluid mechanics and thermodynamics.
